Title: Attachment hook for grape vines and fruit bushes - consists of two hooks for fixing wire
Inventor: REISACHER JOSEF DR ING
IPC: A01G17/10
Filed: 1974-10-05
Abstract: The hook can be made of plastic-coated iron wire, and is suspended on both sides with two hooks. Both enclose the grape-vine.

Title: Personal sound proofing against surrounding noise - having signal adapted interference suppression whilst maintaining aural determination of directions
Inventor: QUANTE FRANZ
IPC: A61F11/14
Filed: 1974-12-20
Abstract: The equipment has two microphones and a dual channel amplifier built into it. The microphones can imitate the directional characteristics of the human ear. The amplifier can be coupled to a probe microphone so that running machine sounds can be checked for faults at specific points on a very noisy machine. A signal adapted interference suppressor can be built into the amplifier. Frequency selected filters can be used to filter out high power density spectral regions without affecting understanding of normal levels of speech. The amplifier can be regulated to switch off at given intervals to protect against periodic noise peaks ie when a hammer or press is in use.

Title: Filter for removing tar mist from air stream - having cylindrical filter bags on which tar adsorbing layer of powder is laid
Inventor: KAWASAKI TAKUYA
IPC: B01D46/30
Filed: 1976-04-13
Abstract: Tar mist is removed from an air stream by forming layers of fine powder or gas permeable carriers, these being cylindrical and vertically mounted above a collector with a depression on the downstream side. The powder is laid by means of an air stream in which it is suspended which is passed through the carriers. The tar mist contg. air is then passed through the carriers in the same direction with a reduced press. being maintained behind the carriers. Finally the spent powder is vibrated off the carriers and collected in the hopper below. The signal to proceed to the cleaning stage is derived from the increasing resistance of the powder layer to the air flow. Suitable powders are clay, diatomaceous earth, perlite or fly ash-individually or as mixts. To remove tar mists from air streams to prevent atmospheric pollution, esp. in the prepn. of carbon electrodes. Tar tends to fluid and contaminate cloth filters and cover electro-static precipitators with a layer of insulating tar. The system provides a soln. to this problem and gives a practical means of removing such mixts.
